Submarine volcanoes, such as Kolumbo (Santorini, Greece) are natural laboratories for fostering multidisciplinary studies. Their investigation requires the most innovative marine technology together with advanced data analysis. Conductivity and temperature of seawater were recorded directly above Kolumbo's hydrothermal vent system. The respective time series have been analyzed in terms of non-e...

This paper uses a two-region, two-period overlapping generations model with international labor mobility to examine the efficacy of using tax policy to internalize the externalities created by international labor migration. While a brain drain tax has a substantial limiting effect on labor migration and a small negative effect on per worker growth, it is found to be a viable solution to the neg...

Shell structures, especially cylindrical shells, are widely used in aerospace and naval architectural industries. Submarine hulls and aircraft bodies can be idealized as cylindrical shell structures. The study of vibrations of cylindrical shells is an important aspect in the successful applications of the cylindrical shells. The free vibration characteristics of a submarine hull have an importa...

W HiLE conceptual and methodological problems of defining mental health and its presumed opposite, mental illness, have been considerable, some areas of agreement are begin-' ning to appear among the many psychiatrists, psychologists, and social workers active in this field.' More and more, the most useful criterion of mental illness appears not only to be related to the incidence and severity ...

The empirical probability of submarine mass failure is quantifi ed from a sequence of dated mass-transport deposits. Several different techniques are described to estimate the parameters for a suite of candidate probability models. The techniques, previously developed for analyzing paleoseismic data, include maximum likelihood and Type II (Bayesian) maximum likelihood methods derived from renew...

On May 15th of this year, I provided you with preliminary findings from the Congressional Budget Office (CBO) study of issues related to submarine programs now under review by the Congress. In that earlier letter, I addressed the near-term savings that would result from a decision not to fund completion of the third Seawolf submarine. After briefly reviewing those savings, the accompanying atta...

Simulations of self-propelled submerged bodies have been conducted in idealized environments with simple environmental geometries and stratifications. The focus of those simulations was on improving the submarine performance, including reduced drag, less vortex production, improved maneuverability and greater speed. Thus, many of the simulations focused on the near field and on complex, realist...

Flexible and scalable networking solutions are required to offer more efficient bandwidth allocation and increased connectivity in submarine networks. In this regard, filterless optical networks based on agile edge nodes equipped with coherent transceivers and passive broadcast-and-select nodes are promising cost-effective options which allow for more flexible capacity allocation and resource o...
